C-2
JP5, the Port Address jumper:
The WDP Reader in Bus Interface mode can use any of four different port
addresses: hex 220, 240, 2C0 and 2E0. The default setting is 220, which most
people will be able to use with no problem.
Occasionally a tape controller, bus mouse, network board, real-time clock or other
add-on may be using address 220 (compare add-on board switch settings with the
manuals) and you'll need to choose another.

setting if you are installing the WDP Reader in external or internal wedge mode.
